What is alternate angle definition?

Definition of alternate angle : one of a pair of angles with different vertices and on opposite sides of a transversal at its intersection with two other lines: a : one of a pair of angles inside the two intersected lines. — called also alternate interior angle.

What is alternate angle with example?

Alternate Interior Angles are a pair of angles on the inner side of each of those two lines but on opposite sides of the transversal. In this example, these are two pairs of Alternate Interior Angles: c and f.

What is the definition of alternate exterior angles?

Alternate exterior angles are formed by a transversal intersecting two parallel lines . They are located “outside” the two parallel lines but on opposite sides of the transversal, creating two pairs (four total angles) of alternate exterior angles.

What are alternate angles kids definition?

Alternate interior angles – When a third line called the transversal crosses two other (usually parallel) lines, angles are formed on the inside, or interior, of the two lines. The angles that are opposite of each other are the alternate interior angles.

What is alternate interior angles class 9th?

Alternate interior angles are the angles formed when a transversal intersects two coplanar lines. They lie on the inner side of the parallel lines but on the opposite sides of the transversal.

What is the sum of alternate angles?

Alternate Interior angles are congruent. The sum of the angles formed on the same side of the transversal which are inside the two parallel lines is equal to 180°. Alternate interior angles don’t have any specific properties, in case of non-parallel lines.

How alternate angles are formed?

Alternate angles are formed between parallel lines after they are cut by a transversal. They don’t have the same vertices and fall on the alternate side of the transversal.

What is the value of alternate angle?

The sum of the angles formed on the same side of the transversal which are inside the two parallel lines is always equal to 180°.
